More than two-thirds of the global population will experience a traumatic event during their lifetime, and almost 6% will go on to develop post-traumatic stress disorder (PTSD). These numbers highlight a vital truth: trauma is common, but subsequent PTSD is not inevitable.
Many of us may be unsure about the difference between the two terms, but understanding the distinction can help us heal one another in deeper ways.
What separates trauma from PTSD, and why is that difference so critical?We’ll give you coping mechanisms to help if trauma is starting to dominate your life or the life of someone you love.
What’s the difference between trauma and PTSD?
Broadly speaking, the difference between trauma and PTSD is found in how a traumatic event affects a person and how long the body’s response to the trauma continues.
Some events and situations are clearly traumatic for most people, like war, a natural disaster, being assaulted, or suffering the loss of a loved one. There are other, less overt situations where the trauma is not so apparent, like when a child changes schools or is in a minor car accident.
We should first look a little more closely at the definition of both terms.
Defining trauma
Trauma refers to a person’s experience during and after a life-threatening or extremely distressing event. To better help a person process a traumatic event, psychologists break trauma down into three types: chronic, acute and complex trauma.
- Acute trauma usually relates to one single traumatic event, like a natural disaster or a car accident.
- Chronic trauma means it is ongoing and repeated, such as childhood neglect, abuse, or bullying.
- Complex trauma is understood as a combination of both acute and chronic trauma.
Any of these forms left unaddressed in your mind and body may progress into PTSD, which is a specific mental health diagnosis.
Defining PTSD
Post-traumatic stress disorder is a recognised mental health condition that can happen after trauma, but it is not guaranteed in every case.
PTSD can develop after experiencing a shocking, dangerous, or otherwise scary event. People with PTSD often feel stressed even when they are no longer in any danger. Symptoms of PTSD may start straight after the traumatic event, or they may lie dormant before emerging years later.
Symptoms for PTSD sufferers can include:
- Unwanted recollections of the traumatic event
- Reliving the trauma through mental experiences, like gunfire sounds or the odour of an abuser
- Heightened sense of danger
- Emotional numbness or a desire to avoid situations that remind them of the past
- Intense and vivid nightmates
Unlike trauma, which may fade or be processed over time, PTSD tends to persist or intensify without the right support.
Why this distinction matters
It is not uncommon for trauma and PTSD to be used interchangeably, even by well-meaning friends and helpers. However, misunderstanding their difference may hold someone back from getting the right level of support they need.
If trauma is treated as PTSD, treatment will generally be unsuitable. Imagine a person processing grief after losing a loved one, and their friends quickly tell them that they have PTSD. PTSD is a clinical label with a structured framework of treatment. This person may then start to look online for help or falsely tell a treatment provider they have the disorder, hindering the treatment process.
Conversely, a person deeply who has PTSD might be told by people around them to simply “move on,” as “everyone experiences trauma at some point.” This person is struggling with a diagnosable condition and may benefit from professional intervention or medically-assisted therapy, as the condition has rooted itself deeply into their nervous system.
Understanding the distinction empowers both the suffering person and the treatment provider. Trauma-informed support, early intervention and PTSD treatment all depend on accurate recognition. We hope to have conveyed the key differences between the two terms as we endeavour to get people the right support they need for healing.
How does PTSD affect people differently?
Not every person who goes through trauma will develop post-traumatic stress disorder, and not every person reacts to traumatic events in the same way. If two people go through the exact same traumas, one might develop PTSD while the other person doesn’t. It is important to remember this before searching for blanket symptoms for each traumatised person.
That being said, you may have a higher risk of developing PTSD after trauma due to factors which include:
- Women are more likely to experience PTSD than men. 10% of women have PTSD in their lifetime, compared to 4% of men, and gender identity may also affect a person’s risk.
- People who have served in the army may be at high risk, with research showing 1 in 1,000 people in the British Armed Forces suffer from PTSD. Further research suggests that those deployed in Iraq and/or Afghanistan have a higher rate than those deployed elsewhere.
- Experiencing trauma earlier in your life is likely to increase your chance of developing PTSD. Research shows that PTSD prevalence increases by 28% with each additional childhood trauma type.
The significance of adverse childhood experiences (ACEs)
Adverse childhood experiences, or ACEs, refer to traumatic events that occur before the age of 18. ACEs include physical, emotional, or sexual abuse, neglect, witnessing domestic violence, or living with a caregiver who struggles with behavioural addiction or mental illness.
As clinical psychologists and behavioural experts continue to explore the subconscious drivers of addiction, there is a growing consensus that ACEs directly relate to substance and alcohol addiction later in life.
Studies show that people with four or more ACEs are significantly more likely to develop substance use disorders, depression and anxiety later in life.
In England, almost half of all people have experienced at least one ACE, with almost 10% experiencing four or more. Tragically, further research shows that having 6 ACEs can make a person live, on average, 20 years less than people who haven’t experienced any.
We hope that shining a light on the profound and shadowy influence trauma has can start to provide help for addiction and help as many people as possible come to terms with painful memories and childhood experiences.
Healing doesn’t mean forgetting: coping strategies
If you’re struggling with the symptoms of PTSD or unresolved trauma, there may be times when disturbing sensations overwhelm your day. We hope you can use some of these coping strategies to help:
- Lean on a support group and loved ones: Are you making the most of your loved ones or a dedicated support group? PTSD flourishes in isolation, so make sure you’re not cutting yourself off. Seek out help from family, friends, or a group who have been through similar trauma as yourself.
- Use grounding techniques: People with PTSD will sometimes experience depersonalisation or derealisation. You may, at times, catch yourself feeling detached from everything around you. You might not notice the room you’re in, the smells, colours and sounds that permeate the air, or your reality can feel distorted and dreamlike. Remind yourself where you’re located. Take your shoes and socks off and root to the ground, and try reaching out and touching objects with different textures.
- Engage in positive self-talk: You may find that recurring voices in your head are often self-deprecating and disparaging. Try deliberately talking to yourself more nicely. “I’ve handled this before, I’ll do it again.” “I am safe. Just breathe.” Strive to make your internal voice kinder.
- Seek professional treatment: Finally, please remember that you aren’t alone, and you aren’t beyond recovery. Research from the WHO states that 40% of people with PTSD recover within one year, through treatment for the condition. Reaching out to professional treatment providers may be the key that unlocks the door to the recovery you deserve.
Where can I get help for PTSD, trauma or behavioural addiction?
Whether you’re dealing with the aftermath of trauma, living with PTSD, or struggling with drug addiction linked to your past, support is waiting.
At UKAT, we understand the deep and sometimes hidden connections between trauma and substance use. That’s why our treatment focuses not just on the symptoms, but the root causes that drive them.
You don’t need to carry the burden alone. Reach out today and let’s take the first step of recovery together.
